Modelling and reconstruction of landscape evolution and landslide dynamics in the Central Mountain area of Taiwan
In our Land Dynamics group a considerable amount of landscape system modelling experience has been gained over the past years. A major problem is lack of suitable data sets which allow calibration and validation of such models at the appropriate temporal and spatial resolution and extent.
In cooperation with National Taiwan University and Kainan University
So far it has been impossible to separate water driven surface erosion from gravity driven landslide components in current landscape evolution studies and modelling approaches. Furthermore, It is important to understand the human induced erosion sediment contribution. To solve the aforementioned issues we propose to study the landscape process dynamics of the 763.4 km2 Shihmen watershed (Taiwan). Our results will contribute to a better understanding of the sediment supply of rivers draining mountainous catchments. In addition, It is of societal relevance to understand to what extent the river sediment supply can be controlled by managing human factors to prevent damage to (drinking) water reservoirs. The study will give insight in the adaptive capacity of mountainous areas.
